Hello from Italy! I have studied Mirabilis Jalapa for a while as I have it in my garden and decided to try the leaves and roots so me and my husband had our leaves infusions and made capsules from the dried powder roots. It really have a anti viral effect as we got the flu and it lasted for 1 or 2 days with a very low fever while we usually stay sick for at least 1 week with high fever. The root has aphrodisiac effect on my partner, he also noticed his genitals bigger. As he has a bit of asthma, I can tell you that he breaths much better and felt less pain for his sciatica inflammation. As for me, while I was preparing the root capsules in powder I got some dermatitis on my face and didn't take the risk to orally consume it. I am happy with only the leaves which are very good for intestinal flue, anti-bacterial and constipation, too. This is the way I prepared the drugs:
I dried the roots and then turn it into powder in my blender then I took 250mg capsules and made it ready to be consumed. For the aphrodisiac effect he uses from 4 to 5 capsules a day. As for the leaves, I used it dried in hot water but they can also be used fresh.
Hope this was useful. Best wishes. CIAO!
